Letters Patent No. 101,341, dated March 29, 1870.

BASE BURNING `FIREPLACESTOVE.

The Schedule referred to in theleLettm Patent and mldng part of the lume.

I, WILLIAM E. Woon, of Baltimore, in the county of Baltimore and State of Maryland, have invented certain Improvements in Stoves, of which the following is a specification,

Nature and Objects of the Invention.

The first part of my invention relates to the combination with a stove fora fireplace or hot-ail' furnace, of a series of communicating downward and upward-draught fines, and clean-out chambers beneath them, in such a manner that a duplicationof the usual down and up draught between the fire-chamber ofthe stove and the escape-due of the chimney is afforded in both sides of -the body of the stove,- the object of this part of my invention being to aiford increased heat-radiating surfaces in the down and up draught-fines of such stove, with facility for removing the dust'and ashes which ane deposited by the ucs.

The second part of my invention relates to the combination with the magazine fuel-cylinder above the fire-pot, and a hot-air receiving and distributing chamber above the said fuel-cylinder, of an air-heating space surrounding the magazine fuel-cylinder, and communicating at lower end with fresh-air-supplying tubes, and at its upper end wit-b theair-receiving and distributing chamber above it, in such a manner that a steady current of air will enter the said air-heating space around the magazine fuel-cylinder, become heated therein, and eventually discharged through perforations in -the hot-air receiving and distributing chamber' above.

Description of the Accompanying Drawings.

Figure 1 is a perspective view showing the backand one side ofthe stove.

Figure 2 is avertical section of lig. l, through the back lines.

Figure 3 is a vertical section of fig. 1, through the side lines, and clean-out chambers ot one side of the stove.

Figure 4 is a vertical central section parallel with thefront of the stove.

General Description.

A, B, C, D, and E `are the series of communicating downwardand upward-draughtilues at each side of the stove; and

F and G the cleanfout chambers beneath A, B, C, and D.

h the usual dircct-draught due; and

t its clean-out chamber below it.

K is the magazine or fuel-cylinder; and

L, its surrounding air-heating space, both o f which are suspended together within the fire-chamber m abm'e the incandescent fuel in the fire-cylinder n.

o o are the ii-esh-air tubes which, passing through fire-chamber m, communicate with the external air, and-the air-heating space L of the magazine or fuelcylinder K.

P-is the hot-air receiving and distributing chamber which communicates -through a series of holes 1-1, with the said air-heating space L,'and allows the said hot-air to. escape through a series of holes 2 2 in the top of the chamber I.v

The fuel is introduced through a feed-tunnel, q, which passes through the chamber "1.

The clean-ont chambers F and G are separate and distinct from each other, and aretitted with a. removable door, 3, in front, which allows ready. access to their interior for removing ashes and dust.

The ilue A at each side of the stove conducts the hot products of combustion from the upper end of the,

chamber m, down int-o the space F, from which they are conducted upward through the flue B, and along the flue C into the ue D, which conducts them down into the space G and i to the upward fines E and h, through which they reach the escape or chimneyline. a

Access for removing the ashes and dust vfrom the space 'i is afforded by the stopper 4, (see tig. 1,) while an opening to the direct-draught flue h to allow the ashes to enter the same while the hre` is being raked, is afforded by a valve, 5, which is operated in front through the ash-box.

It will now be understood, without further description, that, by meansof the communicating. down and up fines A- B C D E, and the separate clean-out chambers F and G, an increase of heat-radiating surface will be-produced with ready access in frontfor removing the falling dust and ashes therefrom, and that a larger amount of heated air will be supplied to the room through the distributing-chamber P, by means of the air-heating chamber L, from the same amount of fuel consumed.

Olaf/m.

I claim as my invention- 1. The combination with the stove for al tire-place or hot-air furnace, of the series of downward and upward-draught ues A B O D E, and' clean-out chambers F and G, substantially as and for the purpose hereinbefore set forth.

2. The combination with the magazine fuel-cyl-in der K, of the air-heating chamber L, the fresh-air snrplying tubes o o, and the hot-air receiving and dis tributing chamber P, substantially as and for the purpose hereinbefore set forth.
